I browsed google and found nothing so thought i would put my efforts up here.
hope this all helps.

this function will allow you to return the number of days between two dates minus saturdays and sundays. (including the start date)

// ########## startMonth and endMonth both start at 0 i.e 0 = january, 1 = feb etc
function getDaysMinusWeekend(startDay, startMonth, startYear, endDay, endMonth, endYear) {
	var sdate = new Date();
	var edate = new Date();
	var odays = 0;
	var total = 0;

	sdate.setFullYear(startYear,startMonth,startDay);
	edate.setFullYear(endYear,endMonth,endDay);

	odays = 6 - sdate.getDay();
	if(odays == 6) {
		odays = 0;
	}

	sdate.setFullYear(startYear,startMonth,startDay + odays);

	return Math.floor(((((edate.getTime() - sdate.getTime()) / 1000 / 60 / 60 / 24) / 7) * 5) + 

odays);
}

Hi, is there a possibility for the public holidays to be excluded as well aside from weekeds? Thank you.

Yes, it's possible, but then you'll need a lookup table containing those dates
